but if you ask me I would:
1. tryed to find out from wich country he is from
2. then tryed to find out from wich town/village he is from
3. tryed to find out his real name and surname and then add him on facebook
4. work in cover and arange meeting in r/l with him (even if you have to represent yourself as girl just to meet him in r/l)
5. kick his ass (kick him like vola u kupusu <--- use google for that) so bad that he remembers you all his life
6. tell your friends about it and look cool.
cheers
